Description

Condensation water generator for agricultural protection net

Technical field:

The invention relates to a device for collecting air condensed water, in particular to a generator for collecting air condensed water by adopting an agricultural protective net.

Background technique:

In areas with high temperature and high humidity, especially subtropical and tropical areas, such as islands, deserts and other areas where fresh water resources are scarce, water use often becomes a major local problem, especially fresh water. Existing islands or desert areas obtain fresh water mostly by transporting it from other places, but the cost of this method is too high, and if the transport equipment breaks down, there will be no fresh water supply for a period of time, affecting agricultural production and people's lives. Another way is to use the rainwater collection system to collect and treat rainwater during the rainy season to meet the requirements of drinking water or other water use; however, the way of collecting rainwater is very easy to be restricted by the environment, and the rainfall is insufficient or the temporal and spatial distribution of rainfall is not good. Both may lead to insufficient water supply. If it is on an island, the rainy season is often accompanied by typhoons, mixed with seawater. Compared with land rainwater, the salt content is higher, and it is easily affected by seabird feces and sea sand infiltration and dissolved minerals in the collection site. , the quality of the collected rainwater is not good, and it is not easy to drink for a long time. In addition, for the residents or stationed personnel on the island, fresh water can also be obtained through seawater desalination, but the water quality indicators such as transparency, turbidity and taste of the freshwater obtained by seawater desalination are not ideal, and it is not easy to obtain long-term drink.

In order to further improve the efficiency of producing condensed water, there are multiple condensing pipe units installed on the protective net. Preferably, the condensation pipe units may be evenly distributed on the protection net. Such an arrangement can improve the generation efficiency of condensed water.

In order to further improve the condensing effect, the condensed water of the condensing pipe unit flows from bottom to top.

In order to ensure that the efficiency of cooling and condensing water in each area is the same, a pressure regulating valve is arranged at the water inlet of the condensation pipe unit.

In order to further improve the multifunctionality of the protective net, the density of the protective net is 10-50 mesh.

In order to further improve the collection efficiency of the condensed water generator, a refrigeration system is arranged in the protective net.

The beneficial effects that can be brought by adopting the protective net condensation water generator of the present invention are:
